@entlicher,@everflux; I can not reproduce the issue. Can you please give me the steps ?

I can tell you that I am using Ubuntu 16.04 Gnome, but I have no idea what triggered the bug.

@Revivius: Regarding the code UIManager.getColor("Button.darcula.color1") or UIManager.getColor("Button.darcula.color2") is null

Please make com.revivius.nb.darcula.ui.ContentAreaAwareToggleButtonUI NPE safe, when colors are not set in UIManager.
